RIO MACHO HYDROELECT

closed

The Rio Macho Hydroelectric Project will provide power generation, as well as diesel generating capacity, and, although the initial capacity of the hydroelectric scheme will only be 30 MW, tunnels and other essential features will suffice for an ultimate capacity of 90 MW. The generating plant will consist of two 15 MW sets, with provisions for a plant expansion to a total of six 15 MW sets at a later date. A tailrace (760 meters in length approximately) will carry the waters from the power plant to the Reventazon river. The project includes an outdoor step-up substation adjacent to the power plant, outdoor step-down substations at Colima, Barranca, and La Garita, with some 80 kilometers of 138 KV single circuit transmission line. Additionally, diesel generating plants, consisting of two 4 MW sets, will be installed at the Colima station, another two 0.5 MW at Limon station, on the East Coast.
